Measurement of the single top quark t-channel cross section with a template fit analysis

We present a measurement of the inclusive single top t-channel production cross section in proton-proton collisions at the LHC, using data collected with the CMS experiment during 2011 and 2012. The analyzed data correspond to an integrated luminosity of 1.17/1.56 fb−1 for muon/electron channel respectively at the centre-of-mass energy of 7TeV, and to 5.0 fb−1 at 8 TeV. The analysis exploits the pseudorapidity distribution of the recoil jet and reconstructed top-quark mass using background estimates determined from control samples in data. The measurement is used to determine the CKM matrix element |Vtb|
